Additional Practice Questions
What are the environmental impacts of burning fossil fuels like petrol and diesel?
mediumAnswer: Burning fossil fuels releases greenhouse gases, leading to air pollution and contributing to climate change. It also affects health due to smog and reduced air quality.
What are some alternative energy sources that can be used instead of fossil fuels?
easyAnswer: Alternatives include solar energy, wind energy, hydroelectric power, and biofuels. These sources are renewable and have lower environmental impacts.
Design a small experiment to demonstrate the concept of energy conservation.
hardAnswer: Gather two cars, one running on petrol and another on electricity. Measure and compare the efficiency and emissions over a week. This demonstrates the difference in energy conservation between fossil and alternative fuels.
Describe how the pricing of fuels affects everyday life and economic activities.
mediumAnswer: Fuel prices impact transportation costs, influencing the price of goods and services. High fuel costs can lead to increased inflation and economic strain on consumers.
Explain the process of oil refining and its importance in fuel production.
